Abstract

A glow plug (10) is proposed which serves to ignite a vaporized fuel/air mixture in internal combustion engines. This glow plug (10) surrounds with its annular metal casing (11) an electric heating pin, from the end of which projects a connection screw (14). An insulation jacket (25) is slid over this connection screw (14), thus filling the gap between the connection screw (14) and the metal casing (11). In the region of this insulation jacket (23) the convection screw (14) and/or the metal casing (11) are provided with annular projections or recesses (28) which protect the connection screw against tensile forces. The connection screw (14) is, however, also provided with at least one projector (31) or one recess (30) protecting it against torsion in the longitudinal bore too, projections (29) or recesses can also be provided which resist torsion of the connecting screw (14). The head of the connecting screw, which possesses the projections (31) or recesses (28, 30) and may if necessary also carry the connection thread (19), is produced preferably as a separate component (14/2) and seccured to the connection screw (14).
